だけでなく (dake de naku)
～だけでなく — not only ～ but also ～
Pattern
-
名詞 ＋ だけでなく、～も子どもだけでなく、大人にも (not only children but also adults) -
普通形（な形容詞は〜な） ＋ だけでなく、～も安いだけでなく、品物もいい
Add one more
The first half is limited to the obvious or basic point, and the second half adds a surprise or a bigger point: 安いだけでなく品物もいい. The pair is almost always completed by も in the second half.
Compared with ばかりでなく
だけでなく is neutral and used in both speech and writing. ばかりでなく is a bit more formal. 〜のみならず is the most formal written form. All of them express the same idea of adding more.
Examples
-
この店（みせ）は安（やす）いだけでなく、品物（しなもの）もいい。
Kono mise wa yasui dake de naku, shinamono mo ii.
This shop is not only cheap but also has good goods.
-
この公園（こうえん）は子（こ）どもだけでなく、大人（おとな）にも人気（にんき）がある。
Kono kōen wa kodomo dake de naku, otona ni mo ninki ga aru.

-
彼（かれ）は約束（やくそく）を守（まも）るだけでなく、いつも早（はや）めに来（く）る。
Kare wa yakusoku o mamoru dake de naku, itsumo hayame ni kuru.
He not only keeps his promises but also always arrives early.
Common mistakes
- Keep the second half in the same direction as the first. Do not add something contrary after it.
- A particle goes after だけ in the first half if needed: 子どもだけでなく、大人にも.
